I found that by getting in better physical shape I have much less aches and pains. Not so much weight loss but building strength in your body. I went to a seminar on being fit while aging. It opened my eyes to the problems of being weak, feeling tired and getting more unhealthy while getting older. No matter your limitations, there are simple exercises to do that will make a great improvement in how you feel. One thing they had everyone do was to sit straight in the folding chair, arms straight down by our sides and raise up out of the chair using only our legs and stand straight up. It was amazing how many of the younger folks could not do it and some of the elderly could do it several times. People in wheelchairs or had back/knee/hip/feet problems had different exercises to do to show their level of fitness.
